Flailing limbs in the water is a clear indicator of a swimmer in distress because it signifies that the swimmer is struggling to stay afloat or is unable to maintain control in the water. Such erratic movements can suggest panic, exhaustion, or a potential drowning situation. Swimmers in distress often lack the ability to swim efficiently and may resort to instinctive responses like thrashing about, which can further hinder their ability to stay above water.

In contrast, other choices do not typically signify distress. Clear and loud shouting might suggest a swimmer who is seeking help or trying to communicate but does not inherently indicate they are in distress, as they may be capable of remaining afloat. Consistent swimming strokes suggest someone who is swimming effectively and is likely in control, not in distress. Lastly, the presence near the pool edge can indicate a swimmer is simply resting or preparing to enter the water rather than signaling trouble. Therefore, recognizing flailing limbs is crucial for lifeguards to react swiftly to potential emergencies.
